WINDTMILL.

SPECIFICATION forming part of Letters Patent No. 449,744, dated April '7. 1891.

Application filed November 15, 1890. Serial No. 371,545. (No model.)

To all whom, it nuty concern.-

Be it known that I, HUGH NOONE, a subject of the Queen of Great Britain, residing at Osceola, in the county of Polk and State of Ne braska, have invented certain new and useful Improvements in \Vindmills; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in windmills of that class generally known as vertical solid wheel, and which are generally thrown out of gear by a horiZontally-swinging tail-vane.

The object of the invention is to simplify the mechanism heretofore provided for throwin g the mill in gearand dispose the parts composing the same in such relation to the other parts of the engine that they will be balanced in high winds and thrown in and out in a positive manner when liberated from controlling forces.

A further object of the invention is to reduce the number of parts and increase the efficiency of the engine, and at the same time construct a mill that will perform its work in a satisfactory manner and which is capable of being easily handled in a gale.

The improvement consists in the novel features and in the peculiar construction, arrangement, and adaptation of parts, all as more fully hereinafter described and claimed, and which are fully shown in the accompanying drawings, in which- Figure 1 is a side view of a windmill embodying my improvements. Fig. 52 is a detail view of the governor mechanism for throwing the mill into gear, showing the relative arrangement of the parts.

The tower 13 is of well-known construction, being composed of four corner-posts, which are suitably braced and united at their upper ends by the casting 4, which is constructed to overlap the ends of the posts and extend along the sides thereof for a short distance to receive the fastening-bolts, which secure the said posts to the casting. The casting 4 is centrally apertured to permitthe passage of the pump-rod, which is composed of the parts 10 and 12, that are coupled together by a swiveljoint in any of the well-known ways. The turn-table 5 is mounted on the casting 4, so as to turn freely thereon, and is provided with suitable bearings at diametrically-opposite points in which the wheel-shaft6 obtains bearings. This shaft 6 is provided with a crank between its hearings to which the upper portion of the pump'rod is attached and by which the said rod is operated. The wheel 9 is secured on the outer end of this shaft 6, and is strengthened by the stay-rods A,which extend from the disk at at the outer end of the shaft 6 to the wheel, being connected with the latter a short distance from the periphery thereof. The ring B on the rear side of the wheel receives the thrust and the wear of the brake-shoe b on the end of the rod 8, the latter being horizontal and secured to the vertical spring-standards 3 3, that project up from the turn-table 5. The standard 3 nearest the tail-vane 7 is provided with a block 1), against which a corresponding block b on the tailvane impacts when the mill is out of gear and holds the brake-shoe b on the ring B, thereby preventing any motion of the wheel on its axis. The tail-vane 7 is pivoted to the turntable, substantially as shown, to one side of a plane, passing vertically through the axis of the wheel.

The governor mechanism is composed of the weighted lever ll, the rod 15, a yielding connection 16, and the rod E. The yielding connection comprises the rod D, having stop (Z at one end and an eye at the opposite end to which the chain or rope E is connected, the other end of the chain or rope being connected with the free end of the weighted lever 11. A spring 0 is mounted on the rod D, and is confined between the stop (Z and the end of the rod 15, which is bent to embrace the same. stands in a horizontal position with its weighted end away from the tail-vane. The cord F, for throwing the mill out of gear, passes over suitable guides, and is connected with the tail-vane in such a manner as to serve to throw the same toward the wheel when pulled upon.

In practice, to throw the mill out of gear The weighted lever normally.

the ropeor cord 11 is pulled upon with sufficient force to fold the tail-vane upon or parallel with the wheel. As the tail-vane folds, the block b strikes against the block b", and applies the brake-shoe l) to the wheel. During this operation the weighted lever is elevated from a nearly horizontal to an approximately vertical position. On releasing the rope F the weighted lever assumes its normal or horizontal position and throws the mill into gear, the brake-shoe being withdrawn from contact with the wheel by the elasticity of the spring-standards 3 3.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is

1. In a windmill, the combination, with the wind-wheel and the tail-vane, of a governor composed of the weighted lever 11, mounted on the tower or frame, the rod 15, and a yielding connection between the end of the rod D, connected with the said lever, and the rod 15, connected to the vane, substantially as set forth.

2. In a windmill,- the combination, with the wind-wheel and the tail-vane, of the weighted lever 11, mounted on the tower, the rod I), having a stop (7 connected with the weighted lever, the spring C on the rod l), and the rod 15, connected at one end with the tail-vane and having its other end bent to embrace the rod D and bear on the spring 0, substantially as specified.

3. A windmill comprising the following elements: a tower, the casting 4c, secured to the upper end of the tower, the turn-table mounted on casting 4 and provided at diametricallyopposite points with bearings, the wheel-shaft mounted in the said bearings, the wheel held on the shaft and braced by the stay-rods A and having ring B, the yielding standards 3 3, the horizontal rod 8, having the brake-shoe b, the tailwane adapted to operate the rod 8 and apply the brake, the weighted lever 11, mounted on the tower, the rod 15, connected with the vane, the yielding connection 16, composed of the rod D, having stop (Land the spring 0 between the weighted lever 11 and the rod 15, and the pun1p1od, substantially as and for the purpose specified.

In testimony whereof I a'ffix my signatn re in presence of two witnesses.

HUGH NOONE.
